Leprosy - eliminated and forgotten: a case report.

BACKGROUND: Leprosy is a disease that was declared eliminated in 2010 from Nepal; however, new cases are diagnosed every year. The difficulty arises when the presentation of the patient is unusual. CASE PRESENTATION: In this case report we present a case of a 22-year-old Tamang man, from the Terai region of Nepal, with a clinical presentation of fever, malaise, and arthralgia for the past 2 weeks with hepatosplenomegaly and bilateral cervical, axillary, and inguinal lymphadenopathy. Features of chronic inflammation with elevated erythrocyte sedimentation rate of 90 mm/hour and liver enzymes were noted. With no specific investigative findings, a diagnosis of Still's disease was made and he was given prednisolone. On tapering the medication, after 2 weeks, the lymphadenopathy and fever reappeared. On biopsy of a lymph node, diagnosis of possible tuberculosis was made. On that basis anti-tuberculosis treatment category I was started. During his hospital stay, our patient developed nodular skin rashes on his shoulder, back, and face. The biopsy of a skin lesion showed erythema nodosum leprosum and he was diagnosed as having lepromatous leprosy with erythema nodosum leprosum; he was treated with anti-leprosy medication. CONCLUSION: An unusual presentations of leprosy may delay its prompt diagnosis and treatment; thus, increasing morbidity and mortality. Although leprosy has been declared eliminated, it should not be forgotten and physicians should have it in mind to make it a differential diagnosis whenever relevant.

Two atypical presentations of lepra reactions.

Leprosy or Hansen's disease is a chronic infectious granulomatous disease with varied presentation, especially in the setting of lepra reactions. We report two such atypical presentations each of Type I and Type II Lepra reactions; the first being an elderly male presenting with fever, while the second case being of a young boy being evaluated for cervical lymphadenitis.

Coinfección por lepra y tuberculosis ganglionar en un adulto / Leprosy and ganglionar tuberculosis coinfection in an adult

Se describe el caso clínico de un paciente de 34 años de edad, quien acudió a consulta de Dermatología por presentar máculas eritematosas pruriginosas generalizadas. A los 3 meses con tratamiento específico comenzó a presentar febrículas vespertinas y adenopatías cervicales dolorosas, por lo que se indicó una baciloscopia en ambos codos y pabellones auriculares, pero no se halló el Mycobacterium leprae; además se realizó biopsia por aspiración con aguja fina de un ganglio cervical, cuyo resultado reveló una tuberculosis ganglionar. Finalmente se diagnosticó una coinfección por lepra y tuberculosis ganglionar, dos enfermedades producidas por el Mycobacterium, cuya coexistencia es rara.

The case report of a 34 year-old patient is described who came to the Dermatology Service due to disseminated pruritic erythematous stains. After 3 months with specific treatment he began to present evening low fevers and painful cervical adenopathies, reason why a baciloscopy was indicated in both elbows and ear pavilions, but the Mycobacterium leprae was not found; besides aspiration biopsy with fine needle of a cervical ganglion was also carried out, which result revealed a ganglionar tuberculosis. Finally a leprosy and tuberculosis ganglionar coinfection was diagnosed, two diseases emerging due to the Mycobacterium, which coexistence is strange.

Immunocytochemical detection of mycobacterial antigen in extrapulmonary tuberculosis.

The aim of the study is to determine whether immunostaining for mycobacterial antigen can contribute to the cytological diagnosis of extrapulmonary tuberculosis (EPTB). The study was carried out on aspirated material of lymph nodes, and other accessible sites, from 65 patients with clinical diagnosis of tuberculosis (TB). Twenty patients, diagnosed by fine-needle aspiration, with non-tuberculous granulomas served as controls. The diagnosis of TB was based on the demonstration of acid-fast bacilli (AFB), culture positivity for Mycobacterium tuberculosis (M. tuberculosis), or response to treatment with standard anti-tubercular therapy. Immunostaining was done using polyclonal antibody to mycobacteria. AFB positivity by Ziehl Neelsen (ZN) staining was 21%, 65.38%, and 68% respectively in Pattern 1 (granulomas alone), in Pattern 2 (granulomas with necrosis), and in Pattern 3 (necrosis alone). Overall AFB positivity was 56.92%. Twenty-eight of 65 cases were negative for AFB on direct smear. Culture was positive in 46% (13/28). Sensitivity and specificity of immunostaining were 96.92% (63/65) and 95%, respectively. Immunoreactivity was seen in 26 (92.8%) of 28 cases which were negative by ZN staining. Except in the case of leprosy, in which cross reactivity was seen, there was no immunoreactivity in the control group. Immunocytochemistry (ICC) had high sensitivity (96.2%) and specificity (95%) in the diagnosis of EPTB. ICC may be a useful adjunct to evaluation of cytomorphology and ZN staining.

Cutaneous tuberculosis is a specific form of tuberculosis, with various clinical pictures and resulting from either endo- or exogenous way of infection, immunological mechanisms and unfavourable conditions for mycobacterium development. The atypical course and symptoms of the disease may cause difficulties in obtaining proper diagnosis and, in consequence, result in delayed onset of appropriate treatment. When diagnosing cutaneous tuberculosis, a broad spectrum of differential diagnoses should be applied, taking into account other diseases, such as, among others, leishmaniasis, actinomycosis, leprosy or deep mycoses. In this report, a case of lymph node tuberculosis and of colliquative tuberculosis of the skin, at first erroneously diagnosed as actinomycosis, complicated by multiform erythema. In the reported case, no tuberculous bacilli were identified in bacteriological evaluations of bioptates, collected from the skin changes. The final diagnosis of the disease was determined by the presence of specific granulation tissue in the last of performed histopathological studies, as well as by hypersensitivity to tuberculin and the presence of mycobacterial DNA in PCR evaluation. According to the authors, in case of clinically suspected cutaneous tuberculosis, repeated (several) histopathological studies of samples from observed changes seem to be fairly justified. The results of histopathological studies should be completed by one of the methods of oligomycobacterial material evaluation, e.g. by identification of mycobacterial genetic material by means of nucleic acid amplification in the PCR method.

Dermatomyositis in a human immunodeficiency virus infected person.

It is interesting to study an autoimmune condition like dermatomyositis (DM) in the setting of immunosuppression due to human immunodeficiency virus (HIV) infection. An HIV seropositive female aged 30 years, presented with a nonitchy rash over the face, breathlessness, diarrhoea and difficulty in raising her hands above her head. A heliotrope rash around the eyes, Gottron's papules and proximal muscle weakness were found to be present. C reactive protein, erythrocyte sedimentation rate and lactate dehydrogenase levels were raised, but creatinine phosphokinase and anti-nuclear antibody profile were normal. Her HIV serostatus was confirmed by Western blotting, keeping in mind the potential for false positive HIV serology in an autoimmune disorder. Her CD4 count was 379 cells/mm3. An X-ray of the chest showed bilateral pleural effusion with raised pleural fluid adenosine deaminase levels. Clinical findings and laboratory investigations favored the diagnosis of DM and HIV infection with tuberculous effusion in an HIV seropositive patient. She was treated with antibiotics, four-drug anti-tubercular treatment, systemic steroids and later, antiretroviral treatment. Chances of a false positive antibody test for HIV should be considered in a patient having an autoimmune disease such as DM.

Lepromatous lymphadenopathy and concomitant tuberculous axillary lymphadenitis with sinus. A case report.

A 25-year-old male patient with florid lepromatous leprosy presented with right axillary lymphadenopathy and a discharging sinus. He also had scabies with chronic right otitis media. Histopathological examination of the lymph node revealed lepromatous lymphadenitis coexisting with tuberculosis. This unusual combination of two different clinical entities is recorded in this case report.
